Q. How do blood tests help guard your health?
A. These tests help to reveal the condition of your blood so that
your physician can detect "hidden" diseases that are often diffi
Scult to diagnose in their early stages. Many doctors use blood
tests as a regular part of periodic physical examinations. So if
your doctor suggests a blood test, don't worry. He is using, for
your benefit, one of the valuable procedures of medical science.
Q. What does a blood count tell your doctor?
A Checking the number, size, shape, and condition of your blood
cells is called a blood count. The number of red cells and the
Amount
of hemoglobin in them is one of the indices which help
reveal your general physical condition. A count of white cells
may be of value in diagnosing certain diseases. It is sometimes
combined with the sedimentation test, which establishes the time
taken by blood cells to settle.
Q. What will chemical analysis of the blood show?
A Your blood is composed chiefly of water, salt, sugar, fat, and
proteins. Chemical analysis of the blood is used to determine
whether or not these and other components are present in normal
amounts. This is important in aiding the diagnosis of certain
diseases. For example, excessive sugar, salts or waste products in
the blood indicate conditions requiring medical treatment.
